In the communication between Smart ID Identity Manager and the ADCS, the following components are involved:

Identity Manager Server

• The Identity Manager server contains CA-Server and CA-Name, and connects directly to the Connector ADCS.
  
• The integrated CA Proxy connector is used as proxy for the client machines.

IIS Webserver - Connector ADCS

• The IIS Webserver with the ADCS Connector does not need to be installed on the ADCS-Server, but on a server in the same domain.
• Identity Manager authenticates with a client certificate on the ADCS Connector. 
• The ADCS Connector uses a Domain Service Account, which has the required rights in ADCS.

Certificate Authority (CA)

• This is the ADCS server. The Domain Service Account of the connector is used to request and publish certificates from and to the CA.
